Where can I find a Boulder car rental if I am younger than 25?
Some Boulder outlets will rent to drivers under 25 years old, and others won’t. Age policies differ between suppliers, so you should do your homework. Also, find out if there are any additional costs. Some outlets will pass on a surcharge to young customers between the ages of 21 and 24. Always read through the terms and conditions to avoid any nasty surprises.
